Geotechnical load cells TOR-IDRA/M


Download PDF

The toroidal hydraulic load cell TOR-IDRA/M measures changes in workload on rods and anchors subjected to tension, allowing in this way to evaluate carefully the possible losses for release during exercise or pressure increases, due to thrust on the ground containment structures.

The cell consists of two steel plates of a circular shape, with a central hole to allow the passage of the strands, machined and welded together in such a way as to create an interspace filled by a special oil and connected to a precision pressure gauge on which you can directly read the value of the load in KN.

MOUNTING OF THE LOAD CELL

General precautions to be followed in the installation and assembly of load cells:

  • Follow the direction of application of force on the load cell
  • Do not exceed the limits of the temperature as indicated in the data sheet
  • Do not remove labels from the load cell
  • Adequately protect the cables with sleeves or channels
  • Carry out on each load cell a ground connection with suitable cable, shunt on mounting accessories
  • Do not carry out any welding on the mechanical structure after mounting the load cell
  • Avoid or reduce to a minimum level any mechanical constraints between the rigid structure and the weighing structure to avoid error in weighing and return to zero
  • In case of vibration or dynamic loads product the load cells with puffers / shock absorbers
  • Protect load cell from any dust accumulation with any appropriate means
